Naomi Alderman looks at the remarkable way Denis Diderot connected ideas and people. In 18th-century Paris, he edited one of the very first encyclopaedias: twenty-eight volumes with tens of thousands of articles on everything from the concept of liberty to cutting-edge medical research, the manufacture of silk stockings and a recipe for apricot jam. Diderot was the perfect man for the job – energised by veering from one subject to the next and undeterred by fierce opposition from the Church or even a government ban on the entire project.
